Market liquidity,closeout procedures and initial margin for CCPs*

ABSTRACT

Closeout procedures enable central counterparties (CCPs) to respond to events that challenge the continuity of their normal operations, most frequently triggered by the default of one or more clearing members. The procedures typically entail three main phases: splitting, hedging, and liquidation. Together, these ensure the regularity of the settlement process through the prudent and orderly liquidation of the defaulters’ portfolios. Traditional approaches to CCPs’ margin requirements typically assume a simple closeout profile, not accounting for the ‘real life’ constraints embedded in the management of a default. The paper proposes an approach to assess how distinct closeout strategies may expose a CCP to different sets of risks and costs taking into account real-life frictions. The proposed approach enables the evaluation of a full spectrum of hedging strategies and the assessment of the trade-offs between the risk-reducing benefits of hedging and the transaction costs associated with it. Using an unexplored set of transactional level data, the proposed framework is evaluated assuming the hypothetical default of a real CCP clearing member. We consider the worst-case loss of a large interest rate swap portfolio observed over the past 10 years (i.e. 2005–2015) and show that an efficient hedging strategy which minimises risk may not be optimal when transaction costs are taken into account. The empirical analysis suggests that transaction costs are a significant factor and should be accounted for when designing a hedging strategy. Specifically, it is shown that the risk-reducing benefits arising from more tailored hedging strategies may introduce higher transaction costs, and therefore may change the effectiveness of the strategies.     

Expressions of Relationship Networking in International Entrepreneurship

The role of networks is a major factor in the internationalization process for entrepreneurs. In this article, we analyze the influence of social networks in international entrepreneurship. We developed a multiple case study based on a qualitative perspective, selecting four fruit exporters from the Brazil’s semi-arid region and used a qualitative and longitudinal design. These firms are among the largest fruit exporters in Brazil. Content analysis was derived by examining organizational documents, bibliographical material, and semi-structured interviews with 30 managers and consultants. We used ATLAS.ti software to analyze the collected material. The major networks were formed with buyers and competitors, affording benefits such as trust and information; relationships were therefore formed in both vertical and horizontal directions. Consequently, and due to their influence on the internationalization process, social networks are considered a relevant subject in international entrepreneurship. Moreover, the expressions of social networking have interfaces with both the exploration of international opportunities and attitude towards risk, as well as the development of competitive features that are the fundamental dimensions of international entrepreneurship. The results reveal that social networks are fundamental to entrepreneurs’ businesses and are strategic for their development and maintenance. Recognition of such role of these networks in international entrepreneurship is the main contribution of this paper.     

Can Agile Project Management Be Adopted by Industries Other than Software Development?

This research paper presents evidence from an exploratory survey on the use of agile project management (APM) practices and the presence of APM enablers in 19 medium‐ and large‐sized companies from different industry sectors considering innovative projects. The results show that these companies are possibly struggling to use their current management practices in the face of different project challenges. Additionally, the presence of some APM enablers indicates opportunities to adapt the APM theory for different companies other than those in software development. Future research should explore the correlation between APM practices and enablers in order to develop “hybrid” management models for different industries.     

Innovation efforts and performances of Brazilian firms

We analyze the relationship between innovation and firms' performance in Brazil using a comprehensive database that cross-references innovation information by PINTEC (Technological Innovation Research) of the IBGE (Brazilian Institute of Geography and Statistics) and financial information from Serasa and Gazeta Mercantil. Results from the structural equation modeling suggest that variables associating with investments in innovation, which are connected to the innovative effort of a company, do not explain financial performance significantly.     

Vertical integration in production and services: development in transaction cost economics

In this paper, we first establish the core, fundamental concepts of Williamson’s TCE, examining the different governance structures or the institutional alternatives that TCE theory proposes. We go on to describe some critical considerations and theoretical proposals that correspond fundamentally to Williamson’s heuristic model, the integration of incentives in organizational forms, idiosyncratic demand, and how the concept of transaction is conceived in general.     

Institutional determinants of downsizing

This study analyses the institutional determinants of downsizing in an economy with a highly rigid labour market: Spain. Our focus is first placed on the impact that the system of severance payment has on downsizing adoption. In particular, we analyse whether the regulatory environment can explain variations in employers' downsizing use. In addition, we analyse how organisations imitate one another in implementing downsizing, presumably in a quest for legitimacy. The evidence provided indicates that low levels of severance payments incurred by downsizers in the past promotes downsizing in the present, but too high severance payments discourages downsizing. Therefore, firms in Spain are constrained by regulatory forces stemming from labour law. Our results also reflect the importance of rational myths in downsizing because companies imitate the decisions on downsizing widely used in their industry and, particularly, those adopted by industry leaders.     

Socially responsible downsizing: Comparing family and non‐family firms

This study seeks to investigate whether family firms are more likely to downsize their workforce than their non‐family counterparts. Drawing on socioemotional wealth approach, we first explore the effect of family presence on workforce downsizing. Furthermore, we examine the moderating role of R&D activity on the family presence–downsizing relationship. Our sample covers a panel of manufacturing SMEs in Spain over the 1993–2014 period. We find that family firms are less likely to downsize than non‐family firms. Our results also reveal a negative association between R&D activity and workforce downsizing. Finally, the relationship between family presence and downsizing is contingent upon R&D activity, that is, family firms engaged in R&D activities are less likely to downsize than non‐innovative family firms.     

Effects of perceived retail crowding: a meta-analytic study

ABSTRACT

We performed a meta-analysis to understand the crowding construct in the retail context. The systematic review identified 535 studies, of which 69 were present in the analysis conducted, generating 504 quantitative relationships. Our meta-analysis indicated that the perception of crowding generates many negative feelings, a few positive feelings, minimal perceived value, low attractiveness of the environment and low short- and long-term consequent behaviours. At the methodological level, it was found that student samples and experiments tend to produce a stronger impact on the relationship between crowding and satisfaction. It was also found that the effect of crowding perception on customer satisfaction differed according to cultural influence. Finally, the results did not demonstrate an influence of the type of density (human vs spatial) on the relationship between retail crowding and satisfaction.     

Checking for asymmetric default dependence in a credit card portfolio: A copula approach

Traditional credit risk models adopt the linear correlation as a measure of dependence and assume that credit losses are normally-distributed. However some studies have shown that credit losses are seldom normal and the linear correlation does not give accurate assessment for asymmetric data. Therefore it is possible that many credit models tend to misestimate the probability of joint extreme defaults.This paper employs Copula Theory to model the dependence across default rates in a credit card portfolio of a large UK bank and to estimate the likelihood of joint high default rates. Ten copula families are used as candidates to represent the dependence structure. The empirical analysis shows that, when compared to traditional models, estimations based on asymmetric copulas usually yield results closer to the ratio of simultaneous extreme losses observed in the credit card portfolio.Copulas have been applied to evaluate the dependence among corporate debts but this research is the first paper to give evidence of the outperformance of copula estimations in portfolios of consumer loans. Moreover we test some families of copulas that are not typically considered in credit risk studies and find out that three of them are suitable for representing dependence across credit card defaults.     

Conditional conservatism and cost of capital

We empirically test the association between conditional conservatism and cost of equity capital. Conditional conservatism imposes stronger verification requirements for the recognition of economic gains than economic losses, resulting in earnings that reflect losses faster than gains. This asymmetric reporting of gains and losses is predicted to lower firm cost of equity capital by increasing bad news reporting precision, thereby reducing information uncertainty (Guay and Verrecchia 2007) and the volatility of future stock prices (Suijs 2008). Using standard asset-pricing tests, we find a significant negative relation between conditional conservatism and excess average stock returns over the period 1975–2003. This evidence is corroborated by further tests on the association between conditional conservatism and measures of implied cost of capital derived from analysts’ forecasts.
